Itls a still further object of this invention to provide a motor driven pump of suitable construction, which pump. as stated, will be operated through the several connectionsior drawing fluid iron: the crank case and successively torcing iiuid into the crank case.

It is a still further object of this invention to provide simme or truck-like structure having wheels to iacilitate the movement 01' the appa- 1| ratus into positions in proximity to the'automobile to be or to be moved to remote places where it can be stored; and it. is furthermore an object to provide the said truck with containers tor the flushing fluid and for the spent-Joli and go fashing fluid during the operations heretoiore An apparatus embodying .the invention has been found to be successful-in use and comparatively inexpensive to produce and maintain. as

With theforegoing and other objects in view, theinvention consists in the details of construction, andin the arrangement and combination of partsto be hereinafter more 'iully set forth and claimed. so

suffice as a detail disclosureot each ofthese parts of the apparatus. The valve II has suitable couplings, generally identifled by the numeral,v

by which it is connected tothe pump II, it being shownalso that these couplings I, are connected through the pipe ll with a master valve mum said master, valve, having a branch or coupling 20, to which a pipe, suchas 'a'h'ose'2l', is connected, which is of such length as'to enter the oil filling tube of a-crank casea'nd descendtherein to the bottom of the crank The master valve has two ports 22 and 22 'inaddition'to the port" 24 leading to thefcoupling 20, and these portsare controlled by a valve 2! which is carried by the valve'stern 26, the said valve stem projecting from the valve and terminating in a handle 21. The

pipe 2| has a section through'which the condition of the circulating fluid canbe observed.

An electrical switch member 2! is mounted'on I the inner end 01' the valve stemjandit coacts with sets of contact terminals 29 and'ill'to bridge the 'gap between each pair of contacts ior establishing electric circuits for. energizing thepump-and the solenoids. The valve 25 is movable" to positions to permit fluid to pass through the port-"into the port 2|, or from the port 24 to theport2l, and when moved to these positions, communication-betweenthe several ports is controlled, that is to say circulation" may be established or interrupted. The'system may be provided with-one or more relief valves ll of known construction, so I that when fluid'is passing through ,the pipes of.

the system, the relieivalve will operate to control one set of pipes of the system. This being a well known mechanical'-'-ieature. it need not; it is thought, be illustrated in detail.

The piping system from the pump opposite piping system comprising the connections-l2; I8

and It may include a pipe 32;connected' with'the port 22 oi the master valve,a pipe it under control of the-valve 34 controlled by the solenoid 34', it being shown that thepipefl connectswith the coupling "33 which communicates with the pump and that th'evalve has a pipeextension 35whichdescends through an opening in the base, so-that it communicateswith'one oi the containers or tanks in the truck. Two such As shown in'Figure 4, there is provided a pair of supply wires or leads l0 and 4|. The lead It is connected to themovable' contact 2!. Fromthe lead-5| extends a conductor, 42 which connects I with one brush of the'motor'M,'the latter being .connected by a shaft 48 and coupling withgthe pump shaft 45. Branch conductors ""and [I e pipe i2 is-connected to a valve l2 and the the connect the lead 4| with one terminal of each of the solenoids l5 and 34 respectively. The remaining terminal of the solenoid I5 is connected by a conductor 48 with one of the contacts 29 and the remaining terminal or the solenoid 34 is connected by a conductor J9 with one of the contacts 20. Conductors 50 and 5| connect the remaining contacts 29 and 30 in multiple with the remaining brush oi' the motor M.

,In the operation ofthe' device, we may consider Fig. 4. When the handle 2'! is in the position there shown, the contact 28 is in neutral position and the device is idle. If the handle 21 be swungto the right, then the contact 28 bridges the contacts "and current will flow from lead to contact 28, one contact 30, conductor 49, solenoid 24',conductor II and back to lead 4|. Also, current will flow from the other contact 30 through conductor 5| and motor M back to lead conductor ll, solenoid l5 and conductor back to lead 4|. At the'same'time, current flows-from the other contact 29 through conductor and motor M back to' lead ll through conductor :42.

Under 'thelast conditions, solenoid l5 and motor M are connected'in multiple. Now, when solenoid ll is energized, valve is opened and valve I3 is held closed by itsspring. v Assuming that tank fl'will'remain closed. Nowfluid will flow'fro'm tank "through pipe |2, pump |'I, pipe 33,'pipe 32, port 22, port-24 and down through pipe 2| to supply flushing oil to the crank case.
